During the observations carried out in the Langtang Khela Valley (Langtang National Park) six mains, easy to recognise, plant communities were recorded. Their distribution depends mainly on two most important factors – altitude and the level of anthropopressure.

The two kinds of shrub communities (temperate Elscholtzia-Colquohinia coccinea and subalpine Rhododendron-Cotoneaster affinis community) and subalpine meadows up to 3600 m probably have anthropogenic origin.
